 desc = "The remote host is missing an update to ntp
announced via advisory USN-705-1.

It was discovered that NTP did not properly perform signature verification.
A remote attacker could exploit this to bypass certificate validation via
a malformed SSL/TLS signature.

Solution:
The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  ntp-refclock                    1:4.2.0a+stable-8.1ubuntu6.1
  ntp-simple                      1:4.2.0a+stable-8.1ubuntu6.1

Ubuntu 7.10:
  ntp                             1:4.2.4p0+dfsg-1ubuntu2.1

Ubuntu 8.04 LTS:
  ntp                             1:4.2.4p4+dfsg-3ubuntu2.1

Ubuntu 8.10:
  ntp                             1:4.2.4p4+dfsg-6ubuntu2.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.
